I think this is brilliant. It's the simple ideas that have the biggest impact. Working in machine vision for twenty years I can tell you, the shop floor guys spend an enormous amount of time trying to get their system to track color and shapes. Constantly re-inventing the wheel.

Fundamentally Pixy acts much like a human eye. It sends info to the brain for it's consideration and has built in ability to separate colors and detect edges.

@Caleb: All I can say is "curse you red barron" ... I was tempted beyond my endurance and I've pledged to the Kickstarter project ... I opted for two sensors because I want to try experimenting with binocular vision...

@Caleb: ...facial tracking is the one that I keep coming back to. Unfortunately they don't show any examples of that working.

I think facial identification and tracking might be beyond this system but ... maybe if you used this system in conjunction with a Parallella -- and you used the Parallella to implement a neural network, then...
